STG3220 Summary of contents
Page 1
... STG3220 has an integrated fail safe function to withstand over-voltage condition when the device is powered off. The STG3220 also has an interrupt pin which sends a signal to the processor when the device is in dedicated port charging mode. Additional key features are fast switching speed, break-before- make-delay time and ultra low power consumption ...
